Chemical characterization of biodegradative threonine dehydratases from two enteric bacteria
(Elsevier, 1982-08-23)
Some chemical properties of the purified biodegredative threonine dehydratases (-threonine hydro-lyase (deaminating), EC 4.2.1.16) from Escherichia coli and Salmonella typhimurium are described. The overall amino acid ...
Initiation of poly-N-acetyllactosamine chain biosynthesis occurs preferentially on complex multiantennary asparagine-linked oligosaccharides
(Elsevier, 1990-08-01)
An N-acetyl-[beta]--glucosaminyltransferase activity involved in the initiation of poly-N-acetyllactosamine chain biosynthesis can be solubilized from Ehrlich ascites tumor cell microsomal membranes. The ability of this ...
Dissecting the Behavior of a Promiscuous Solvate Former Supported in part by the National Institutes of Health Grant R01 AI47450. We thank GMP[verbar]Immunotherapeutics for samples of Bz-423 and Bz-430 and Jeff W. Kampf for the crystal structure determination.

Comparison of the phospholipid requirements and molecular form of CTP: Phosphocholine cytidylyltransferase from rat lung, kidney, brain and liver
(Elsevier, 1980-12-05)
The Cytidylyltransferase activity in fresh cytosol from different tissues of the rat was measured in the absence and presence of phosphatidylglycerol. In all cases addition of this lipid produced large increases in enzyme ...
Isolation and characterization of a glycopeptide from human senescent erythrocytes
(Elsevier, 1983-08-16)
A glycopeptide (called "senescence-factor glycopeptide", SF-G) has been isolated from a tryptic digest of human erythrocytes by specific adsorption and elution from immobilized peanut lectin. SF-G was detectable in old but ...
Seed germination studies I. Purification and properties of an [alpha]-amylase from the cotyledons of germinating peas
(Elsevier, 1966-07-06)
A starch-hydrolyzing enzyme present in extracts of the cotyledons of germinating peas has been purified over 3400-fold. Several independent criteria show that this activity is due to an amylase of the [alpha]-type ...
Identification of the thiol residues involved in modifications of pig heart lipoamide dehydrogenase by cupric ion and by iodoacetamide
(Elsevier, 1974-11-25)
The thiol residues involved in two previously described modifications of heart lipoamide dehydrogenase (NADH:lipoamide oxidoreductase, EC 1.6.4.3) have been identified by comparison of peptide maps of unmodified and modified ...
Activity and some properties of choline kinase, cholinephosphate cytidyltransferase and choline phosphotransferase during liver development in the rat
(Elsevier, 1973-10-17)
The activity of choline kinase (ATP:choline phosphotransferase, EC 2.7.1.32) cholinephosphate cytidyltransferase (CTP:cholinephosphate cytidyltransferase, EC 2.7.7.15) and cholinephosphotransferase (CDP-choline:1,2-diacy ...
Protein---carbohydrate interaction : Part XXI. The interaction of concanavalin a with d-fructans
(Elsevier, 1969-06)
The immunochemical techniques of quantitative precipitation and hapten inhibition have been employed in a study of the interaction of concanavalin A with several levans of bacterial and plant origin. Of the polysaccharides ...
Catabolism of [gamma]-hydroxy[2-14C]glutamic acid by excised leaves of Phlox decussata
(Elsevier, 1964-01-13)
